Bluetooth Headphone

      A Bluetooth headset is a hands-free headset that uses Bluetooth technology to allow users to talk in a variety of ways without the hassle of wires. Since its introduction, the Bluetooth headset has been a great tool for mobile business people to enhance their productivity.

      A Bluetooth laptop is a laptop with Bluetooth wireless communication. In the 10th century AD, when the Norse lords were fighting for supremacy, the King of Denmark stepped forward and, thanks to his tireless efforts, the bloody war was stopped and all parties sat down at the negotiating table. Through communication, the lords became friends. The King of Denmark, who was so fond of blueberries that his teeth were stained blue, became known as the Bluetooth King, and so Bluetooth became synonymous with communication. Today, a thousand years later, when a new wireless communication specification was introduced, it was again named after Bluetooth, a concept first introduced by Ericsson in 1995. The Bluetooth specification works in the microwave band, with a transmission rate of 1M bytes per second and a maximum transmission distance of 10 metres, up to 100 metres by increasing the transmitting power. Bluetooth technology is globally open and has excellent compatibility worldwide, and the world can be connected through a low-cost invisible Bluetooth network.
